· How to get a name of silicon (Si) Silicon was discovered by Jöns Jacob Berzelius, a Swedish chemist, in 1824 by heating chips of potassiumin a silica container and then carefully washing away the residual by-products. [Source] = http://education.jlab.org/itselemental/ele014.html
· Symbol, Atomic number, and atomic mass
1) Atomic Number: 14 2) Atomic Weight: 28.0855 3) Phase at Room Temperature: Solid 4) Element Classification: Semi-metal 5) Period Number: 3 6) Group Number: 14 Group Name: none 7) Symbol : Si
Silicon's atomic number is 14. Therefore it has 14 protons and 14 electrons. Now take the Atomic Mass, and subtract 14 from that number and you should get the right amount of neutrons.
1) Melting Point: 1687 K (1414°C or 2577°F) 2) Boiling Point: 3538 K (3265°C or 5909°F) 3) Density: 2.3296 grams per cubic centimeter 4) Abundance in Earth's crust: second most abundant element in the world.

In the form of sand and clay it is used to make concrete and brick; it is a useful refractory material for high-temperature work, and in the form of silicates it is used in making enamels, pottery, etc. Silica, as sand, is a principal ingredient of glass, one of the most inexpensive of materials with excellent mechanical, optical, thermal, and electrical properties. Glass can be made in a very great variety of shapes, and is used as containers, window glass, insulators, and thousands of other uses. Silicon tetrachloride can be used as iridize glass. Hyperpure silicon can be doped with boron, gallium, phosphorus, or arsenic to produce silicon for use in transistors, solar cells, rectifiers, and other solid-state devices which are used extensively in the electronics and space-age industries. Hydrogenated amorphous silicon has shown promise in producing economical cells for converting solar energy into electricity. Silicon is important to plant and animal life. Diatoms in both fresh and salt water extract Silica from the water to build their cell walls. Silica is present in the ashes of plants and in the human skeleton. Silicon is an important ingredient in steel; silicon carbide is one of the most important abrasives and has been used in lasers to produce coherent light of 4560 A. Silcones are important products of silicon. They may be prepared by hydrolyzing a silicon organic chloride, such as dimethyl silicon chloride. Hydrolysis and condensation of various substituted chlorosilanes can be used to produce a very great number of polymeric products, or silicones, ranging from liquids to hard, glasslike solids with many useful properties.

· Number of protons, element, and neutrons
Silicon's atomic number is 14.
Therefore it has 14 protons and 14 electrons.
Now take the Atomic Mass, and subtract 14 from that number and you should get the right amount
of neutrons.

· Where did we find the silicon
( Silicon Valley ) Silicon Valley is the original home to the semiconductor chip making industry that uses silicon (fine sand!) as a basic raw material, prompting a newspaper writer one day to call it Silicon Valley.
